4. Press firmly on the end of each sprog supported batten and then release. Set the VG to full off and than to full tight
again. Measure the crossbar travel: it should be 130mm. Measure the height of each thread relative to the top of the keel
tube. The results should be as follows:

Note: All figures are given with VG on only.
Permissible range of thread heights relatively to the top level of the keel tube is +/- 5mm.
5. Note that this method will not disclose sprogs that are asymmetric. If, after achieving the proper measurement, you
have a turn in the glider, which is only present at tighter VG settings, lower the sprog on the side the glider is turning
towards, and raise the other sprog by the same amount.
